Common Myths About CBD and THC

Cannabis and its best-known compounds—CBD (cannabidiol) and THC (tetrahydrocannabinol)—have attracted growing interest in recent years. As their popularity has increased, so too have the number of misconceptions surrounding them.

Here are some of the most common myths, along with what current research suggests.

1. Myth: CBD Has Therapeutic Benefits, While THC Does Not

Fact: CBD is widely recognised for its potential therapeutic properties, but THC has also been extensively studied for a range of medical applications.

Research has explored THC's potential role in supporting appetite, reducing chemotherapy-related nausea and vomiting, and managing certain types of pain. Some preclinical studies have also investigated its possible effects in neurodegenerative diseases, although further clinical research is needed.

2. Myth: THC Is Bad and CBD Is Good

Fact: This is an oversimplification.

CBD and THC are different cannabinoids with different characteristics. Neither is inherently "good" or "bad". Their suitability depends on the individual, the intended purpose and the legal framework in which they are used.

Research suggests that the two cannabinoids may complement each other in certain situations.

3. Myth: CBD Works Best Without THC

Fact: Some studies suggest that CBD and THC may work more effectively together than when used separately.

This interaction is commonly referred to as the entourage effect, where multiple naturally occurring cannabis compounds may work together.

Research into this phenomenon is ongoing, and scientists continue to investigate how different cannabinoids and terpenes interact.

4. Myth: Single-Compound Pharmaceutical Products Are Always Better

Fact: Whole-plant cannabis extracts contain hundreds of naturally occurring compounds, including cannabinoids, terpenes and flavonoids.

Some researchers believe these compounds may work together to produce effects that differ from those of isolated cannabinoids alone. This concept is also associated with the entourage effect, although further research is required.

5. Myth: CBD Is Not Psychoactive

Fact: CBD does not produce the intoxicating effects associated with THC.

However, describing CBD as completely "non-psychoactive" can be misleading. CBD may influence mood and emotional wellbeing without causing intoxication or impairment.

A more accurate description is that CBD is non-intoxicating, unlike THC.

6. Myth: Psychoactive Effects Are Always Undesirable

Fact: Whether psychoactive effects are desirable depends on the individual and the context.

For some patients using medically supervised cannabis treatments, THC's psychoactive properties may form part of the overall therapeutic experience. For others, these effects may be unwanted.

The response varies considerably between individuals.

7. Myth: CBD Is Naturally Sedating

Fact: CBD is not naturally sedating in all situations.

Some research suggests that moderate amounts of CBD may support alertness during the day, while other studies have explored its potential role in improving sleep in certain circumstances.

The relaxing effects associated with CBD-rich cannabis flowers may also be influenced by naturally occurring terpenes such as myrcene, rather than CBD alone.

8. Myth: Higher Doses of CBD Are Always Better

Fact: More is not always better.

Some studies suggest that CBD may exhibit a biphasic response, meaning that different doses can produce different effects.

In some cases, lower doses may be as effective—or even more appropriate—than higher doses, depending on the individual and the product.

9. Myth: CBD Is Converted Into THC in the Stomach

Fact: There is no reliable clinical evidence that orally consumed CBD is converted into THC in the human body.

The World Health Organization (WHO) has stated that CBD does not appear to produce effects consistent with THC intoxication and has no evidence of spontaneous conversion into THC in humans.

10. Myth: Legalising CBD Alone Is Enough

Fact: While CBD products are legally available in many countries, researchers continue to investigate the potential roles of other cannabinoids, including THC, in medical settings.

Some healthcare professionals believe that certain patients may benefit from products containing a broader range of cannabinoids, where permitted by law and prescribed appropriately.

Conclusion

CBD and THC are among the most researched cannabinoids found in cannabis, but many misconceptions remain.

Current scientific evidence suggests that:

• CBD and THC have different characteristics and potential applications.

• Neither compound should be viewed in overly simplistic terms.

• Research into cannabis and cannabinoids continues to evolve.

• Individual responses vary, and more high-quality clinical studies are needed.

Understanding the science behind cannabinoids can help people make better-informed decisions and distinguish evidence-based information from common myths.
